New design of yellow sticky card is developed to enhance the catch of western flower thrips (WFT), one of the world’s major pests causing damage to many crops through direct feeding and transmitting tospoviruses. Although thrips are known to perceive visual pattern as well as wavelength reflected from an object, only limited number of studies has been conducted on the effect of shape. Hence we evaluated different shapes of yellow sticky card in the laboratory for their attractiveness to WFT. Using square as a standard shape, choice and no-choice experiments were carried out on other shapes, i.e., triangle, circle, semi-circle, diamond, and rectangle. Circle attracted 2.7 and 1.5 times more thrips as compared to square in choice and no-choice experiments, respectively. To contrast the sticky surface and hence to increase the attraction, three different colors were tested as background. Yellow sticky card with black background attracted significantly more thrips than the one with yellow or green backgrounds. Effect of differential ratio of foreground (sticky area) to the background was also assessed, and ratio of 7.5:1 (background: foreground) was the most effective in attracting the thrips. Based on these experimental results, circular yellow sticky card (r=2.5 cm) with black background (12 cm x 12 cm) was designed. Its effectiveness was compared in a strawberry greenhouse with rectangular yellow sticky card without backgrounds, and it attracted 2.3 times more WFT. In conclusion, sticky card we modified enhanced catch of WFT in both field and laboratory and would be good addition to thrips management program.
